In the accompanying drawings, reference label may be reused to identify similar and/or identical element.
Specific implementation mode
CAC includes tube assembly, which includes compressed air flowing across its multiple pipes.CAC, which is usually located at, works as vehicle Surrounding air is allowed to cross the position of tube assembly when being driven.Each in pipe can be arranged in one or more turbulators Inside.In some instances, turbulator can have repetitive structure such as serpentine cross section, " W " shape cross section, other shapes horizontal Section or their combination, the structure limit spacing transverse to the direction of the air-flow across tube assembly.
Turbulator is made of Heat Conduction Material such as metal and is produced Lai free turbocharger as radiator with helping to dissipate The heat of raw compressed air.It is below the freezing point at ambient temperature and automobile is with the low-down supercharging from turbocharger Limit under under certain loading conditions for running, CAC can generate ice.Icing can be with frozen turbulence device and sensor, this can It generates failure code and pauses or reduce the power to engine.
The size of CAC can increase to increase cooling capacity.However, due to limited free space, increase the size of CAC Influence the peripheral parts in engine compartment.Coolant is to increase the another of cooling capacity to select to air heat exchanger system It selects.However, coolant to air heat exchanger ratio CAC types heat exchanger costly, it is heavier, and include usually than air-air Component more CAC.
Under certain conditions, the dew point of the inner air part of CAC can form water droplet, which can be gathered in turbulator And assemble or be blown into air inlet at certain moment.The water blocking piston engine for flowing into manifold causes to pause or reduces power, and can To set diagnostic trouble code.The density that a kind of method of icing and condensation in CAC is reduction internal turbulence device is reduced to reveal Point increases to the incondensible point of water.By reducing the density of turbulator, icing is unlikely to occur, because of CAC cooling capacities And reduced performance.
The reduction of turbulator density solves two problems, but produces the relatively low work(that may be unsatisfactory for engine performance demand Rate CAC.Because, it is still necessary to making alternatively to obtain reduces the benefit that CAC freezes and condenses, and still keeps the property of CAC Energy.
Multiple density turbulators are used in identical CAC according to the CAC of the disclosure.By along the longitudinal direction and/or laterally Direction, which provides two or more density, can change density.Smaller spacing turbulator have larger air-flow and lower pressure, and compared with Big spacing turbulator has larger pressure and compared with little airflow.Change air-air CAC pipes in spacing contribute to reduce water and/ Or the amount to freeze.
In some instances, greater density turbulator is located at CAC entrance sides, is located at the outlets CAC compared with low-density turbulator At side.In this example, most of cooling performances are implemented, and most of hotter pressurized air be cooled to colder temperature (but Be not it is too low with cause freeze or under dew point to cause to condense).If any one of both phenomenons occur, Allow ice and water to remove the turbulator region in air stream compared with low-density turbulator slowly to consume in air inlet to draw Play pouring for water.The exemplary configuration can also anti-stagnant ice be gathered on sensor and in turbulator region accumulate and block Pipe.
In other examples, turbulator is divided into two or more density in transverse direction.The exemplary configuration generate with On the identical result described to longitudinal configuration.Under low load conditions, most of CAC air is used compared in low-density turbulator Paths of least resistance.This transfers to protect CAC from freezing and reaching dew point.If CAC causes to freeze or condense, relatively low close Ice and water can be discharged balancedly to be consumed by air inlet in degree turbulator.During larger velocity gas stream, the both sides of turbulator are taken in Pressurized air simultaneously provides the performance improved compared with the only CAC of constant density turbulator.
